Calhoun's experiment is akin to the flat earth debate being bandied about the CT scene. The whole earth could be seen as a controlled environment. Along with all the resources to support a 'utopia'. Just like the mice people cannot leave the 'box'. The whole is broken up into different social groups. Each with their own way of doing things. Each wanting what another group has. Fighting one another until the whole eats itself inside out.
sometimes the gods like to trigger people by remote control...
